Comparison of the intraoperative intra-aneurysm pressure gradients among seven off-the-shelf endovascular aneurysm repair devices.
Article in Surgery today, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo evaluate the intra-aneurysm pressure (IAP) after the implantation of various off-the-shelf endovascular aneurysm repair (EVAR) devices and examine its clinical implications.
methodsA retrospective review of 153 EVAR cases for infrarenal abdominal aortic aneurysm (AAA) with bilateral common iliac landings and no residual type I/III endoleaks was conducted. During EVAR, the IAP and abdominal aortic pressure (AAP) were measured, and the aorta-aneurysm systolic pressure gradient (AASPG = systolic AAP - systolic IAP) was compared among the devices and between the graft fabric materials. The associations between the AASPG and postoperative AAA shrinkage were also assessed.
resultsThe AASPGs (mmHg) for the devices were as follows: Aorfix (34 cases), 17.8 ± 12.9; Endurant (32 cases), 22.3 ± 16.9; AFX (26 cases), 17.5 ± 18.0; Zenith Alpha (20 cases), 25.7 ± 16.3; Excluder (16 cases), 26.4 ± 19.7; TREO (13 cases), 30.5 ± 11.8; and Alto (12 cases), 37.7 ± 14.5 (p = 0.002). Polytetrafluoroethylene grafts showed a higher AASPG than woven polyester grafts (31.3 vs. 22.5 mmHg, p = 0.009). No significant association was observed between the AASPG and AAA shrinkage.
conclusionThe degree of IAP reduction differs according to the EVAR device and graft fabric material. These findings provide baseline data on the device-specific effects of IAP.
